I never thought about how hard it would be to establish longitude when sailing without a watch. Apparently, it’s really hard. And very deadly when you have no clue how far you are from seeing land again. Luckily there was a big contest with a big prize (₤20,000!) in the 18th century for someone to figure out a reliable system to establish longitude. And someone one it (well, mostly). This book was the story of that. Nice.
Apparently it was also a movie with Michael Gambon (Dumbledore) and Jeremy Irons. It was billed as a thriller on the cover, but I’m not sure how thrilling it was. The story is great, but not on the edge of your seat enthralling. How could someone sitting in their shop making a watch be that riveting? Oh well. It was worth a read. Now if I can only get 9 more books like that, I’ll be able to read 50 by December 31st.
